Frequently asked

"Credentials rejected" right after creating a token

New R2 tokens take about a minute to activate. Buckotto retries automatically — wait a moment.

Still rejected

You may have pasted the raw Cloudflare API token. Paste the S3 Secret Access Key (the SHA-256 value shown once) instead.

I see "No Buckets"

Your token is object-scoped and cannot list buckets. Type the bucket name(s) when prompted, or add a Cloudflare API token to list them automatically.

A bucket says "not found"

Check spelling and jurisdiction — EU buckets use a different endpoint, which Buckotto detects from the endpoint URL.

A file won't preview or play

Its stored Content-Type is wrong. Fix it in the info panel (⌘I).

A share link doesn't work

Your Mac's clock may be off — signed links are time-based. Check Date & Time settings.
